Passed 70-413 yesterday with score 8xx. Used Certifychat June 6 2016 together with Lead2Pass 15.113. Some new questions, some wrong questions and some reworded questions but nothing to worry about. Used CBT Nuggets, together with YouTube, Google and real life experience. Be careful! Some questions you can't revert to after clicking "next" in the exam. Read the instructions carefully. Good Luck.
